The array is situated at the Hat Creek Radio Observatory in Shasta County, 290 miles (470 km) northeast of San Francisco, California.. So, we would expect that there is a lot that Nick couldn't decode. [1][2] The message was aimed at the current location of M13, about 25,000 light years from Earth, because M13 was a large and relatively close collection of stars that was available in the sky at the time and place of the ceremony. The chances advanced beings can pick up the message but not decode and see it as a “first contact” message seems very, very low. The content of the Arecibo message was designed by Frank Drake, then at Cornell University and creator of the Drake equation, who wrote the message with help from Carl Saganand others. [3] When correctly translated into graphics, characters, and spaces, the 1,679 bits of data contained within the message form the image shown here. the size is given. A graphic of the approximate shape of the double helix in which double-stranded DNA polymers naturally exist; the vertical bar in the middle is a binary representation of the number of nucleotide base pairs in the human genome. The readings for 8, 9, and 10 are a little different, as their binary code has been distributed across an additional column next to the first (to the right in the image). I will continue to do for subsequent overlapping areas without A graphic depicting the Solar System, showing the Sun and nine planets in the order of their distance from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Matt Hughes. [1], The message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope in Puerto Rico on 16 November 1974. ten at the right. We’re made of meat! If this is a confusing explanation or you noticed a mistake in my decoding, please let me know and I'll try to improve my answer! The chemical groups from which the nucleotides of polymeric DNA sequences are built – the sugar deoxyribose, phosphate, and the four canonical nucleobases used in DNA – are then described as sequences of the five elements that appear on the preceding line. To one acquainted with polymers, this suggests the chain may four billion, intended to give the approximate human population. the elements of which DNA is composed. the same size as the list of elements give the number of atoms of bottom.). The appearance of the identical backbone sequence at both the left The cosmic communiqué, known as the Arecibo message, carried information about numerical figures, the makeup of DNA, a figure of a human, and a graphic of the solar system. The Allen Telescope Array (ATA), formerly known as the One Hectare Telescope (1hT), is a radio telescope array dedicated to astronomical observations and a simultaneous search for extraterrestrial intelligence (SETI). The bottom row contains markers which indicate the column from which the binary code for each number is intended to begin. by John Walker The pixels marked in red are the binary digits of the Describe a pixel as an element of a digital image. The numbers from 1 to 10 appear in binary format, to be read from the top down. The Arecibo Radio Telescope has collapsed. this is one of the most striking components of the message. 30,618 centimeters, or about 306 meters. [7] The alternative arrangement, 23 rows by 73 columns, produces an unintelligible set of characters (as do all other X/Y formats). to provide a key to the section immediately below in the message. more about the overall structure of DNA from where the groups appear Even assuming that any extraterrestrial recipients would recognize binary, the encoding of the numbers may not be immediately obvious because of the way they have been written. For instance, instead of ASCII's encoding of 65 for "A" and 66 for "B"...we might consider using the number 15621226033 for "A" and 16400753439 for "B". The crop circle is a near replica of the Arecibo message. I am not aware of any connection between the two, other than perhaps the Arecibo message was an inspiration for the SETI project. an extraterrestrial who resembled a human being, this would There's a fun online encoder and decoder… figure) and a number at the very bottom giving its approximate: binary 100101111110 or decimal 2430 units of the 12.6 centimeter numbers of the four chemical elements of which DNA is composed, and I was inspired to create it by the famous Arecibo Message, which attempted to convey humanity's physics knowledge without assuming a cultural context other than math. The Arecibo Radio Telescope has collapsed. [5], The message consists of seven parts that encode the following (from the top down in the image):[4], The entire message consisted of 1,679 binary digits, approximately 210 bytes, transmitted at a frequency of 2,380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 450 kW. Encode a B&W image in binary representing both the pixel data (intensity) and metadata (width, height). Message'. In the "cosmacelf" Yahoo group for the 1802, on April 7th 2010, Steve Gemeny offered a bit of assembly code into their files archive called "arecibo".

Directly below the numbers, which provide the key for interpreting relationship between them, is a cartoon depicting a human being. The value depicted is around 4.3 billion, which was believed to be the case when the message was transmitted in 1974; it is now known that there are only approximately 3.2 billion base pairs in the human genome. 246 1.3k 2 A binary message beeper for the Arduino demonstrating the Arecibo message Project Owner Contributor Arecibo message from an Arduino. , is a simple illustration of a digital image we need to discover order...
